	@doc:	webview
	@keyterms:
		An embedded webview widget,
	@title:
		webview
	@type:
		class
	@short:
		Provides web support in a widget using webkit.
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		Provides an embedded web browser using webkit. Page structure can be managed by web element's unique identifiers.
	@functions:
		!fn: $load(<url:string>)
		Sets the current URL for the webView and starts loading it
		!fn: $setHtml(<html_code:string>,[<baseurl:string>])
		Sets the content of the web view to the specified <html_code>.
		External objects such as stylesheets or images referenced in the HTML document are located relative to <baseurl>.
		The html is loaded immediately; external objects are loaded asynchronously.
		!fn: $findText(<txt:string>,[flag 1,flag 2,..;string])
		Finds the specified string, in the page, using the given options.
		Valid flags are:
		[pre]
			FindBackward		- Searches backwards instead of forwards;
			FindCaseSensitively	- Changes the behaviour to a case sensitive find operation.
			FindWrapsAroundDocument	- Restart from the beginning of the document if the end was reached and the text was not found.
			HighlightAllOccurrences	- Highlights all existing occurrences.
		[/pre]
		!fn: <array> $frames()
		Returns an array containing the names of the document frames.
		!fn: appendWebViewActionToMenu(<menu:h_object>,<webview_action:string>,[<icon_identifier>])
		!fn: <id:integer> $firstChild(<element_id:integer>)
		Return the identifier of element's first child.
		!fn: <array> $findAll(<element_id:integer>,<query:string>)
		Searches for all the elements named <query> and stores them in an array of element's identifiers.
		!fn: <id:integer> $findFirst(<element_id:integer>,<query:string>)
		Searches for the first element named <query>; returns the identifier.
		!fn: <id:integer> $parentElement(<element_id:integer>,)
		Returns the parent of <element_id>.
		!fn: <id:integer> $nextSibling(<element_id>)
		Returns the element just after <element_id>.
		!fn: $appendInside(<element_id>,<html_code>)
		!fn: $appendOutside(<element_id>,<html_code>)
		!fn: <string> $elementTagName(<element_id>)
		Returns the tag name of the <element_id>.
		!fn: <id:integer> $getDocumentElement([frame_name:string])
		Return as unique identifier the document element of the frame [frame_name].
		If no value has been specified for [frame_name], the main frame of the page will be used.
		!fn: string $attributeNames(<element_id>)
		Returns a comma-separated list of the attribute names set on element <element_id>.
		!fn: string $attribute(<element_id>,<name:string>)
		Returns the value of the attribute <name> for element <element_id>.
		!fn: setStyleProperty(<element_id>,<name:string>,<value:string>)
		Sets the value of the inline style on element <element_id> with the given name to <value> .
		In order to ensure that the value will be applied, you may have to append "!important" to the value.
		!fn: <value:string> styleProperty(<element_id>,<name:string>,<style_resolve_strategy:string>)
		Returns the value of the style with the given name using the specified strategy. If a style with name does not exist, an empty string is returned.
		Possible value for <style_resolve_strategy> are:
		[pre]
			CascadedStyle  - the property's value is determined using the rules defined in the document's stylesheet. [b]This is the default strategy[/b].
			InlineStyle    - the property's value is determined by element definition, without respecting CSS rules.
			ComputedStyle  - the property's value is determined by the style property resolved from the environment.
		[/pre]
		!fn: pixmap $makePreview()
		Returns a 212x142 thumbnail of the current webView constants.
		The returned object is an instance of the pixmap class.
		!fn: string $toPlainText(<element_id>)
		Returns the string representation of element <element_id>.
		!fn: string $setPlainText(<element_id>)
		Set the string representation of the  element <element_id>.
		!fn: $setElementAttribute(<element_id>,<name:string>,<value:string>)
		Sets the attribute <name> with value <value> to the element <element_id>.
		!fn: $setWebSetting(<name:string>,<value:bool>)
		Enables or disables the <name> setting depending on <value>.
		Valid settings name: JavascriptEnabled, PluginsEnabled, JavascriptCanOpenWindows, JavascriptCanAccessClipboard, ZoomTextOnly, LocalContentCanAccessFileUrls.
		!fn: $removeFromDocument(<element_id>)
		Removes the element <element_id> from the document.
		!fn: $removeClass(<element_id>,<class_name:string>)
		Removes a class from the element <element_id>.
		!fn: string $classes(<element_id>)
		Returns a comma-separated list of classes set on the element <element_id>.
		!fn: $setLinkDelegationPolicy(<policy:string>)
		Sets the link delegation policy: what happens when the users click on a link. Valid values:
		[br] DontDelegateLinks: No links are delegated. Instead, webView tries to handle them all.
		[br] DelegateExternalLinks: When activating links that point to documents not stored on the local filesystem or an equivalent then $linkClickedEvent() is executed.
		[br] DelegateAllLinks: Whenever a link is activated the $linkClickedEvent() is executed.
		!fn: $linkClickedEvent()
		This function can be called when the user clicks on a link, depending no the current link delegation policy.
		The argument of the function is the URL that has been clicked.[br]
		The default implementation emits the [classfnc:webview]$linkClicked[/classfnc]() signal.
		!fn: $loadStartedEvent()
		This function is called when the load of the page has started.
		The default implementation emits the [classfnc:webview]$loadStarted[/classfnc]() signal.
		!fn: $loadProgressEvent()
		This function can be called during the page load progress.
		The argument of the function is an int value that represent the loading progress status, ranging from 0 to 100.[br]
		The default implementation emits the [classfnc:webview]$loadProgress[/classfnc]() signal.
		!fn: $loadFinishedEvent()
		This function is called when the load of the page has finished.
		The argument of the function is a bool value that is true if the page has been loaded successfully, false otherwise.[br]
		The default implementation emits the [classfnc:webview]$loadFinished[/classfnc]() signal.
		!fn: $downloadRequestEvent()
		This function is called when the user tries to download a file.
		The argument of the function is the URL of the file.[br]
		You should return a valid path in the filesystem where to save the file.[br]
		The default implementation emits the [classfnc:webview]$downloadRequest[/classfnc]() signal.
		!fn: $downloadProgressEvent()
		This function can be called during the download of a file.
		Three integer arguments are passed to this function: the number of downloaded bytes, the download ID, the size of the remove file (if known).
		The default implementation emits the [classfnc:webview]$downloadProgress[/classfnc]() signal.
		!fn: $downloadCompletedEvent()
		This function can be called when a file download finishes.
		The argument of the function is the an integer value containing the download ID.
		The default implementation emits the [classfnc:webview]$downloadCompleted[/classfnc]() signal.
	@signals:
		!sg: linkClicked()
		This signal is emitted by the default implementation of [classfnc:webview]linkClickedEvent[/classfnc]().
		!sg: loadStarted()
		This signal is emitted by the default implementation of [classfnc:webview]loadStartedEvent[/classfnc]().
		!sg: loadProgress()
		This signal is emitted by the default implementation of [classfnc:webview]loadProgressEvent[/classfnc]().
		!sg: loadFinished()
		This signal is emitted by the default implementation of [classfnc:webview]loadFinishedEvent[/classfnc]().
		!sg: downloadRequest()
		This signal is emitted by the default implementation of [classfnc:webview]downloadRequestEvent[/classfnc]().
		!sg: downloadProgress()
		This signal is emitted by the default implementation of [classfnc:webview]downloadProgressEvent[/classfnc]().
		!sg: downloadCompleted()
		This signal is emitted by the default implementation of [classfnc:webview]downloadCompletedEvent[/classfnc]().
